std::filesystem::directory_iterator::directory_iterator

文件系统：：目录[医]迭代器：：目录[医]迭代器

directory_iterator((1)(since C++17)
explicit directory_iterator( const std::filesystem::path& p (2)(since C++17)
directory_iterator( const std::filesystem::path& p, std::error_code& ec (3)(since C++17)
directory_iterator( const directory_iterator& ) = default;(4)(since C++17)
directory_iterator( directory_iterator&& ) = default;(5)(since C++17)

p.如果p

参数

例外

1%29

noexcept规格：

noexcept

2%29std::filesystem::filesystem_error如果发生错误。异常对象是用p作为一种争论。

3%29

noexcept规格：

noexcept

注记

要在当前目录上迭代，请将迭代器构造为directory_iterator(".")而不是directory_iterator("")...
